Answer 1

I was seeing this extra space at the top of one of my table views in a very strange situation.

After I added a UIScrollView as the root view of my first controller in my navigation stack, if I presented the next controller as a Show Detail segue, my next controller would have the space above its table view.

The solution for me was to change the segue to Present Modally and everything went back to normal.

The strangest part of the segue changing was that before I added my root view being a UIScrollView, my Show Detail segue was presenting the next controller modally. Yet after I added the root UIScrollView, the Show Detail segue was pushing on the next controller (which was not what I wanted).
